Neurocutaneous melanosis: a case report
Abstract
Background: neurocutaneous melanosis is a non-hereditary congenital disorder characterized by the association of multiple or large pigmented nevus and an excessive proliferation of melanocytes in the central nervous system. Neurological symptoms are usually of early onset in the infant stage with convulsions of difficult control, making the forecast reserved.
Objective: to present a case with clinical diagnosis of neurocutaneous melanosis with neurological manifestations such as seizures from the infant stage.
Clinical case: a male patient born with a giant melanoma stain that extends from the thorax to the abdomen, inguinal region, genital and lower limbs as a dressing. In the posterior region of the back, it begins in both flanks, sacral region until the misty of both legs, presenting convulsions at one month old. Continuing the appearance of hyperpigmented spots all over the body, which at the age of life are larger darker accompanied by thick hair, with epileptic seizures refractory to treatment.
Conclusions: this disease that is produced by the increase of melanin to the skin and the central nervous system requires a monitoring of dermal lesions and a control of seizures, considering the importance of neurodevelopmental follow-up in a multidisciplinary way for timely intervention if necessary.
